> irq index in deafult shoudl work for t100, you should see interrupts
even with .acpi_ipc_irq_index = 5 the output of the interupts while 
playing is:
pinkflozd@bazdara-t100taf:~$ cat /proc/interrupts | grep sst
    6:          0          0          0          0   IO-APIC 
28-fasteoi   intel_sst_driver

In both situations there is just huge heat coming from the speaker and a 
few clicks not related to playing sound

The T100TAF (Atom Z3535G & rt5642) seems to be using different 
interrupts order than the T100TA (AtomZ3775 & rt5640)

                 Interrupt (ResourceConsumer, Level, ActiveLow, 
Exclusive, ,, )
                 {
                     0x0000001D,
                 }
                 Interrupt (ResourceConsumer, Level, ActiveLow, 
Exclusive, ,, )
                 {
                     0x00000018,
                 }
                 Interrupt (ResourceConsumer, Level, ActiveLow, 
Exclusive, ,, )
                 {
                     0x00000019,
                 }
                 Interrupt (ResourceConsumer, Level, ActiveLow, 
Exclusive, ,, )
                 {
                     0x0000001A,
                 }
                 Interrupt (ResourceConsumer, Level, ActiveLow, 
Exclusive, ,, )
                 {
                     0x0000001B,
                 }
                 Interrupt (ResourceConsumer, Level, ActiveLow, 
Exclusive, ,, )
                 {
                     0x0000001C,
                 }

I did try to sort them (based on Antonios suggestion) but got lots of 
errors when recompiling so i need to explore that a bit further

I did try the "old" driver for SSP0 that the guys with a T100TA are 
using but on the T100TAF doesn't work, so maybe the TAF is using 
something other than SSP2?

Please keep me CC'ed for any followups on this mater

Thanks
